CASA approvals nearly always require that a harness wearer be in a seat with the normal seat belt on and harness removed from the securing point during take off and landing; this ensures that only one release is needed at any time of flight.
Does this really happen ? So the pax take off with their harness unattached and then attach it before they release their seatbelt ? This seems unlikely especially if the attaching point is behind the seat ..and then who checks they have been attached properly? Or I guess the tethers are permanently fixed and you connect your harness to it during the flight .... once again how do you cope with one , of your 4 pax in the back , pulling the wrong part and not being able to re connect .
Maybe I’m missing something!!
